I received both the 1040 ES voucher along with the 1040 v voucher, which should I pay?

Form 1040-V: Payment Voucher is the IRS form that you include with your check or money order when you mail your tax payment for 2016.

You're not required to make 1040-ES estimated tax payments; we're just suggesting it based on the info in your return. If you feel they're not needed for next year's taxes, you can shred them.
